Description

A user with an expired password connected to a server can't assign new password with the statement "SET password=..." if the statement is run in PS mode, for example when it is submitted to server via binary protocol.

Test case is below.

CREATE USER user1@localhost PASSWORD EXPIRE

SET GLOBAL disconnect_on_expired_password=OFF;

connect(con1,localhost,user1);

connection con1;

--error ER_MUST_CHANGE_PASSWORD

select 1;

-- The following statement fails with the error ER_MUST_CHANGE_PASSWORD.

PREPARE stmt FROM "SET password=password('')";

In case the statement

SET password=password('');

is run as a regular statement it is executed successfully.
